Question

What are the two operations we invoke when compiling

A) Linking and loading
B) Preprocessing and linking
C) Compilation and linking
D) Compilation and execution

Answer 1

The two operations we invoke when compiling are Compilation and linking. The final answer is C) Compilation and linking.

Step-by-step explanation:

When compiling, the two essential operations invoked are compilation and linking. Compilation involves translating the source code into an intermediate form, often assembly language or machine code. This phase checks for syntax errors and generates an object file.

Linking, on the other hand, combines multiple object files into a single executable program, resolving references between them. It addresses symbols and ensures the correct memory addresses for functions and variables. This process creates a cohesive and executable program ready for execution. In summary, the correct answer is option C, as preprocessing typically occurs before compilation, and execution is a distinct step that happens after the linking process. Therefore the final answer is C) Compilation and linking.

Answer 2

Compilation involves translating source code into object code, while linking combines object files and resolves references, producing the final executable program. The option C. is correct.

Step-by-step explanation:

Compilation and linking are the two essential operations invoked when compiling code. Compilation involves translating the high-level source code into an intermediate form, often referred to as object code. This step includes lexical analysis, syntax analysis, semantic analysis, and code generation. After compilation, the code is in the form of object files, and linking comes into play.

In the compilation process, the source code undergoes various stages of transformation. Lexical analysis breaks down the code into tokens, syntax analysis ensures proper syntax structure, and semantic analysis verifies the meaning of the code. Code generation then produces the intermediate object code. This series of transformations ensures that the code is correctly translated into a form that the computer can execute.

Following compilation, linking is the subsequent step. Linking involves combining the compiled object code with other necessary object files, libraries, and resolving external references. The linker creates a unified executable file, incorporating all the required components. This final executable is ready to be loaded into memory and executed. Thus, the combination of compilation and linking ensures the successful translation of source code into an executable program. Therefore the option C. is correct.
